Shader doesn't load until window opened in Windows 7 x64

Oh yeah, the other odd behavior that seems to happen with this is that mouse-middle-click in the window of a patch containing this patch brings up the menu, but sometimes quit doesn’t do anything. Quitting from the sub-patch with the shader in it quits, though.

I think this is related to another thread:

enum issue?

This is the first time I’ve run a system with MS updates on. Seems like this stuff worked a couple of weeks ago…

Thanks!
